Eagle Standard Forged Crankshaft 4340 Chromoly Steel

Unlock unparalleled engine performance with the Eagle Standard Forged Crankshaft 4340 Chromoly Steel. Designed to handle the extreme stresses of high-RPM and high-power builds, this crankshaft provides the strength and reliability needed for the most demanding applications. Whether you’re building a race car, dragster, or forced induction engine, this Eagle crankshaft is the perfect choice to take your engine performance to the next level.

Crafted from forged 4340 steel, the Eagle Forged 4340 Crankshaft combines state-of-the-art technology with premium materials to ensure top-tier durability and stability. The center-counterweighted design reduces engine vibration and enhances smooth operation, even under intense stress. Micropolished journals and nitrided surfaces reduce friction, leading to increased longevity and minimized wear, which is critical for high-performance builds.

Whether you’re designing a high-output engine or optimizing for forced induction, the Eagle Standard Forged Crankshaft 4340 Chromoly Steel is engineered to provide the perfect balance of strength and performance. The use of non-twist forging and a hardened nitride surface ensures that your engine will thrive under high horsepower and torque, giving you the competitive edge you need.

Features:

  • Non-Twist Forging – Ensures maximum rigidity, preventing distortion under extreme stress and loads, delivering a durable and stable performance.

  • Center Counterweights – Reduces vibration at high RPM, enhancing engine reliability and stability during high-speed performance.

  • .125" Fillet Radiuses – Strengthens critical areas, adding rigidity to journals for improved reliability in extreme performance engines.

  • Nitrided Surface – Improves wear resistance, extending the life of the crankshaft by providing a hardened surface that resists damage.

  • Micropolished Journals – Minimizes friction for smoother engine operation, enhancing oil retention and reducing wear.

Looking for a crankshaft that can handle the pressures of your high-power engine? The Eagle Standard Forged 4340 Chromoly Steel Crankshaft offers exceptional strength, superior performance, and reliability. Whether you're racing or building an engine that requires heavy-duty capabilities, this crankshaft ensures your engine delivers with precision and stability.

⭐️⭐️⭐️⭐️⭐️

Absolutely incredible crankshaft! I used it in my drag build, and it's been nothing but smooth sailing. The stability at high RPMs is remarkable, and I’ve noticed less vibration. Solid construction, and you can feel the quality right out of the box. Worth every penny!

⭐️⭐️⭐️⭐️⭐️

I’ve been using Eagle products for years, and this 4340 crankshaft is by far one of the best. The fitment was perfect, and I’ve already noticed improved performance in my boosted engine. The nitriding really does make a difference in wear resistance. Couldn’t be happier with my purchase!
